Perfect day (apart from the weather!) ... the bus was comfortable and on time. Our driver was great - very funny and knew everything there was to know about the Space Centre (and space in general). We had the general admission ticket which was OK but there's also an 'ultimate' ticket that I hadn't noticed before but wish I had. This got access to another part of the centre that we only got to drive past. If you are thinking of going to Kennedy then I'd definitely recommend booking through Viator.
We had a great time at Kennedy Space Center. Our tour guide and driver was excellent, and we had a lot of fun.
Trip was awesome, loved the lunch with the astronaut. The best part was the simulator into space. Would highly recommend doing the Space Pass Plus, definitely worth the money.
